METHQD 0F MAKING SHINGLE STRIPS.

Application pled February rial. may be saved by the invention, and I have alsodescribed the process of ycutting such strips from a sheet of roofing material.

By the present invention I vam enabled to produce a shingle strip of a similar sort without any waste 'of material by a diiicrent method of cutting therooing strips.

The invention will be nderstood by referenceV to the accompanying drawings, together with the description, vin 'which Fig. 1 shows, a method' of cutting the shingles; and v Fig. 2 shows a similar method by which the strips are cut so as to-be .of a slightly different shape.

Figs. 3 4, 5 and 6 show diierent methods' of cut-ting shingle strips diiering somewhat in shape from those shown in Figs. 1 and 2.

In Figs. 1 and 2 of the drawings reference character 1 indicates a sheet of rooting material which may be cut into squares along the lines 2, 2' 0r rectangles along the lines 2', 2',`*=-from ,which squares or rectangles smaller squares or rectangles may be cut along the lines 3, 3' and 3', 3', the sheet also being cut along the lines 4 parallel with the lines 2 and 3 or the lines 2" and 3'.a short distance from the` corners made by the 'lines 3 or 3'. The inside smaller square or rectangle may be then cut into individual rectangularly shaped shingles of standard size. Notches may be cut in the edges of the V strips that are to be eXposed-to the weather when the strips are installed on a roof, or the exposed surfaces may be ornamented in various ways already known in this art.

As an example, whena roofing sheet 1, 40 inches wide, isused, the lines 4" may be spaced lOinches from the lines 2 or 10 inches from the sides of the ro ngsheet 1, While the lines 3 are spaced 8 inches from the lines2 on the sides of the roofing material, th'us producing shingle strips having a portion 10 inches wide and 8 inches long, together with a portion.8 inches wide and v1, 1922: sei-iai No. 533,227.

g, as shown in Fig. l. IVith these dimensions the smaller square will be 24 inches by 24 inches, thus making it pos-l sible to cut therefrom six rectangular shingies 8 inches by 12 inches. By making the lines 3 that are parallel to the edges of the sheet 1 an inch and a half longer, standard 30 inches long size shingles 8 inches by 12% inches. can be cut out, thus correspondingly changing the length ofhalf the strips. Other changes in the dimensions may be made without departing from the spirit of the invention.

In the modification indicated in Fig. 2, the saine principle is applied, but.. the interior cut-out portion instead 4of being a square 'may be made with its length greater than its width, thus correspondingly changing the length of the narrow portions of the shingle strips of the new type and making it possible to obtain a greater number of' rectangular shingles from the inside cut-out portion.

In themodifications shown in Figs. `3, 4, 5 and 6 the strips may all be of the same shape cut without waste from sheets of the same width by thediferent methods as indicated, the entire sheet being utilized for making the shingle strips.

In-Fig. 3 reference character 1- indicates a sheet of roofing material that is to be cut transversely alongthe lines 12, 12, and also along the lines 13, 13 and the lines 14, 14, while the same is to 'be cut longitudinally along the lines 15 and 16.

A dierent way of cutting out the shingles is indicated in Fig. 4, the sheet to be cut transversely along the lines 1'?, 17', 17" and also along the lines 18', 18', 18", while the same is to be cut longitudinally along the lines 19 and 20. x

Fig. 5 shows a different method of cutting out the shingles, in which the sheet 1 is cut transversely along the lines 21 and the lines 22, while the same is cut longitu `.nally along the lines 23.

Fig. 6 shows a different method, in which the sheet 1 is cut transversely along the lines 24 and 25, while the saine is cut longitudinally along the lines 26.'

In Figs. 3, 4,5 and 6 the shingle strips are made with the wide portiontwice the Width' to the narrow portion, the preferable length being suchthat the wider portion is about one-fourth the total length of theshingle strip. The edge of the shingle strip that is to he exposed to the Weather when the stripV` is installed on the roof may be notched, or the surface of the same that is to be exposed may be ornamented in various Ways to-iinprove its appearance by methods mentioned above or already 'known in this art.

As a specific example, it may be mentioned that the' shingle strips of this invention may be cut in all the Ways indicated in Figs. 3

to 6 inclusive from a sheet of rooling ma terial 40 inches wide, so as to obtain shingle strips 32 inches long, having the Wider por.- tion 8 inches long Without any Waste of m'aterial Whatever.

I claiinzl. The process which comprisescutting a rectangle from a sheet of rooiing material, cutting a rectangle from the center of said first named rectangle, and cutting the remaining portion so as to form `lour 'shingle strips, each having one end'wid'er than 'the other.

2. The -process which comprises cutting a rectangle from a-sheet of roong material, cutting a ,rectangle from the center of said i'st named rectangle, and cutting the remaining portion along lines perpendicular to the edges at distances from the corners slightly greater than the Width of said remaining portion.

3. The process which comprises cutting a square from a sheet of rooing material, cutting a square from' the center of said first named square, and cutting the remaining portion so as to form four shingle strips each having one end Wider than the other.

4, The process which comprises cutting a iectanglel'fi'oin a sheet of roofing material, cutting a rectangle from the center of said lirst named rectangle, cutting the remaining portion so as to form four shingle strips 1 eacliliaving one end Wider than the other, and cutting said smaller rectangle into rectangular shingles.

. 5. 'llie process which comprises cutting asquare from a sheet of roolingmaterial, cutting a 'square from the center 'of said first named square, and cutting the remaining portion along lines perpendicular to 'the edges at distances approximately one-fourth tlie distance from one corner to the other.

In testimony Whereor` I aHi-X my signature.'
